Frequently Asked Questions
Are robot vacuums worth buying?
Yes, for most homes. Robot vacuums handle daily maintenance vacuuming autonomously, reducing how often you need to manually vacuum. They work best as a supplement to a traditional vacuum rather than a full replacement, particularly for deep-cleaning carpets or stairs.
What is the best robot vacuum for pet hair?
The iRobot Roomba j7+ is the top pick for pet hair. Its rubber dual-extractor rollers resist tangles from long pet hair, and the onboard camera lets it detect and avoid pet waste obstacles automatically.
How often should a robot vacuum run?
For most homes, running daily or every other day keeps floors consistently clean. Homes with pets or high foot traffic benefit from daily runs. The scheduling feature on most models handles this automatically.
Do robot vacuums work on thick carpets?
Entry-level models like the Eufy RoboVac 11S struggle on thick-pile carpets due to limited suction. Mid-to-high-end models with 2,000+ Pa suction, such as the Roborock S8 Pro Ultra, perform well on most carpet types including medium-pile.
What is the difference between a robot vacuum and a robot vacuum mop combo?
A robot vacuum only suctions debris. A combo unit like the Roborock S8 Pro Ultra adds a mop attachment that wets and scrubs hard floors simultaneously. Combo units cost more but reduce the number of cleaning passes needed on hard floors.
How long do robot vacuums last?
Quality robot vacuums typically last 4 to 6 years with regular maintenance. The main consumables are filters (replace every 2 to 3 months), side brushes (every 6 to 12 months), and main roller brushes (every 6 to 12 months).
Can robot vacuums navigate around furniture?
Yes. Most modern robot vacuums use either camera-based or LiDAR-based mapping to build a floor plan and navigate around furniture legs and obstacles. Higher-end models with 3D obstacle avoidance handle cluttered rooms more reliably than older bump-and-go models.
